Trivia / Kamen Rider Fourze

• Actor Allusion:
  • Hayami Kouhei shows up in #13 in a dark red leather jacket - the color of Kamen Rider Garren. Even before that though, Fourze's henshin pose resembled Garren the most, and one Super Hero Taisen Net Movie has Kouhei getting the Garren Buckle!
  • In the net movies, Gentaro actually meets up with Garren and he and Tomoko see a video of Garren...who looks just like their principal. Garren insists that his name is Tachibana Sakuya, not Kouhei Hayami...which Gentaro thinks refers to Meteor's benefactor Tachibana, and his mind starts to overload from confusion.
  • Tokuda Yayoi, played by Rije from Abaranger, could count - Yayoi had issue with being forced through graduation, while Rijie suffered several forced age shifts.
  • And Runa Natsui (Kaoru Shiba/Princess Shinken Red) does get a scene involving swinging something two-handed in #31.
  • In #43, Doctor Maki's Creepy Doll can be seen lounging on Yuuki's front porch. Then we meet her father...
• Backed by the Pentagon: JAXA supported the series; to the point that the Tsukuba Space Center is seen in the opening sequence.
• Bonus Episode: Two, Special Bonus DVD: Astroswitch Secret Report and Hyper Battle DVD: Rocket Drill States of Friendship, were released with an issue of Televi-Kun Magazine.
• Casting Gag: Satoshi Jinbo once played a teacher on a previous Kamen Rider show: Ryuki's Hideyuki Kagawa/Alternative Zero.
• Dawson Casting: Shun is a high school student portrayed by a 22-year-old actor.
• Hey, It's That Place!: The exterior of the Cygnus cult compound in #23 is the same building as Kamome Billiards, where the Narumi Detective Agency is located in Kamen Rider Double.
• Meaningful Release Date: Accidentally. Episode 31, in which Gentaro is killed by Kamen Rider Meteor was released on the same day the actor for Kamen Rider Stronger, Shigeru Araki (whom Gentaro cosplayed in Movie War MEGAMAX) passed away.
• Milestone Celebration: Fourze is romanized as "40", in connection with Kamen Rider's 40th anniversary.
  • According to The Other Wiki, the series is also in commemoration of the 50th anniversary of Yuri Gagarin's feat as the first human in space.
  • Fourze's movies also pay homage to Shotaro Ishinomori by featuring reworked versions of some of his other Toku characters: Everyone, It's Space Time! has villainous versions of the Space Ironmen Kyodain (with their enemies Black Knight and Goblin Queen turned into heroes) trying to take control of a space station based off of Daitetsujin 17. In Kamen Rider × Kamen Rider Wizard & Fourze: Movie War Ultimatum, Fourze mentors a modernized version of Inazuman, Wizard teams up with Bishoujo Kamen Poitrine, and the movie's overall villains are evil versions of the Akumaizer 3, complete with their Cool Ship Zaiderbeck.
• No Dub for You: Fourze managed to avert the franchise's usual fate of No Export for You by being aired in the US on TV Japan, but said network doesn't dub or subtitle their broadcasts.
• Playing Against Type: Nobuyuki Hiyama as the Chessmaster and Man Behind the Man Tachibana who even has a You Have Failed Me moment in #27.
• Promoted Fanboy: As revealed in an interview for the magazine Figure-Oh, JK’s actor Shion Tsuchiya is a fan of the Kamen Rider franchise.
• Prop Recycling: Spares of the first four switches (Rocket, Launcher, Drill, Radar) sometimes get reused as pre-tuned switches - the MagPhone apparently started as a totally black Rocket and Radar. Then there's once-off examples like the gold switch that triggers the Rabbit Hutch locker and even the Core Switch.
• Reality Subtext: As revealed by the production blog after the show wrapped, the scene at the start of the final episode where Yuki reads Kengo's farewell letter after he's been killed by Gamou, was the last scene filmed. According to director Koichi Sakamoto, the KRC's actors had become as close as family over the course of the shoot, thus the tears being shed were their real tears over the fact that they were about to go their separate ways. It was made worse was the fact that Ryuki Takahashi, Kengo's actor, couldn't be on the set for obvious plot reasons. The same blog post had Fumika Shimizu, Yuki's actress, reveal that she actually considered messing up her lines on purpose just so it wouldn't have to end.
• Recycled Script: You'd be surprised just how many connections to Kamen Rider Double this show has.
• So My Parents Can Watch: The reason why actor Sota Fukishi took the role of Gentaro.
  • Played straight for Anna Tsuchiya, who does the opening song for her kids based on much her son loved Kamen Rider OOO back when it aired.
• Star-Making Role: This series helped propel Sota Fukushi and Ryo Yoshizawa into stardom.
• Throw It In!: Fumika Shimizu (who plays Yuuki) actually improvised the Hayabusa song, which the production crew allowed her to record (and used for a later episode).
• What Could Have Been: Originally, Fourze was to have a much stronger anniversary aspect that what we were given. The original plan was to have past Riders appear and team up with Fourze. Sadly, this idea was scrapped because the producers thought it was too soon to have past Riders cameo after Decade.
• Fourze breaks the tradition that W's FangJoker and OOO's TaJaDor of premiering the Mid-Season Upgrade in the Movie Wars film before showing it in the series proper. In this case Rocket States was shown in the movie but Fourze true upgrade is Magnet States, which premiered in the tv show proper.
  • Rocket States did later make a proper appearance in the series, in episode 41.
